Damien Gustav!
The Marquis of America's Deathbane Family. He was also the grandson of Grand Duke Höhn Gustav. Höhn Gustav was the one that traveled with Chen Xiaobei to Paradise Island on the same yacht. During that incident, Chen Xiaobei put a Mother-Child Hexworm in his body. Before Niya made a single move, Chen Xiaobei was afraid that he might betray him at the last minute, So, he appointed Hades to kill him.
After that, his body was tossed into the sea – carried away by the waves and now he was nowhere to be found. Damien Gustav claimed that he could use his sense to find his grandpa's body. That was why he used his connection to ask the US military to help him. Considering that sea waves were constantly moving, that made it very difficult for them to locate the body.
The US officer asked in frustration, "We have been looking for his body for a very long time. Are we just going to stay here until we find the body?"
